BEIJING, Nov. 8, 2024 /PRNewswire/ — WiMi Hologram Cloud Inc. (NASDAQ: WiMi) (“WiMi” or the “Company”), a leading global Hologram Augmented Reality (“AR”) Technology provider, today announced the initiation of exploring the integration of Reinforcement Learning (RL) into the federated learning framework. RL, as a significant branch of machine learning, has become a crucial tool for optimizing the federated learning process due to its decision-making capabilities in complex environments.

Reinforcement Learning is a machine learning approach that enables an intelligent agent to learn optimal strategies through interactions with the environment. In a blockchain-based federated learning framework utilizing reinforcement learning, the reinforcement learning algorithm can dynamically adjust the timing of model aggregation, selection of data participants, and transaction costs. This achieves a balance between information timeliness and data bias, as well as intelligent control over transaction costs, ultimately optimizing the overall learning performance.

In federated learning, there can be significant differences in the datasets of different participants, known as the data bias problem. Additionally, model updates need to be aggregated at the appropriate timing to avoid outdated information affecting overall learning performance. The reinforcement learning algorithm can simulate interactions with the environment to learn when to upload model updates and how to select the most effective models for aggregation under different data distributions. This helps find the optimal balance between information timeliness and data bias. The cost of blockchain transactions, including the consumption of computational resources and network bandwidth, is another important consideration in federated learning. Reinforcement learning can intelligently predict network conditions, resource availability, and transaction priorities to dynamically adjust the frequency and scale of model aggregation. This ensures learning effectiveness while minimizing overall transaction costs. By applying reinforcement learning algorithms to optimize model aggregation strategies, not only does it significantly improve federated learning efficiency and model accuracy, but it also effectively reduces transaction costs.

With the continuous advancement of technology, blockchain-based federated learning frameworks based on reinforcement learning will play a crucial role in various fields such as healthcare, financial services, and the Internet of Things (IoT), promoting the security, efficiency, and widespread adoption of artificial intelligence technology. For example, in the healthcare industry, this framework can facilitate data sharing among hospitals, research institutions, and patients, accelerating the development of disease diagnosis and treatment plans while strictly protecting individual privacy. In the financial services industry, it can assist banks and financial institutions in building more secure and efficient credit assessment and risk management models. In the field of IoT, it enables intelligent collaboration among devices, enhancing the overall network’s responsiveness and intelligence level.

WiMi’s research on the blockchain-based federated learning framework using reinforcement learning represents a significant innovation at the intersection of artificial intelligence, blockchain technology, and reinforcement learning. It provides innovative approaches to address the trust, security, and efficiency issues faced by traditional federated learning. In the future, with further theoretical research and practical applications, the technological potential of blockchain-based federated learning using reinforcement learning will be more fully explored and widely applied in various industry sectors.

Global energy executive joins Prometheus Hyperscale to accelerate sustainable data center growth and provide strategic counsel on $10B flagship project in Evanston, Wyoming

HOUSTON, Nov. 24, 2024 /PRNewswire/ — Prometheus Hyperscale, a leading developer of sustainable hyperscale data centres, is delighted to announce the appointment of Bernard Looney as Chairman of the Board of Directors.

Mr. Looney, former CEO of BP, brings to the role more than three decades of energy sector expertise – from the frontline to the boardroom. He will provide strategic guidance on the development of the company’s growth plans, including its $10B flagship data center in Evanston, Wyoming, which will be among the largest facilities of its kind in the world when completed.

The announcement of Mr. Looney’s appointment comes as societies and large technology companies grapple with how to power the explosive growth in artificial intelligence (AI). The International Energy Agency (IEA) estimates that by 2026 data centers globally will use over 1,000 terawatt-hours (TWh) annually, around the same as Japan uses today. Against this backdrop of soaring demand and squeezed supply, Prometheus is pioneering new standards in hyperscale data center operations.

These approaches include harnessing a variety of energy sources to power its data centers, including renewables, natural gas and possibly nuclear at a later date through our strategic partnership with Oklo. Prometheus aims for its data centers to not impact grid customers.

Another key challenge is the enormous amount of power and water used to cool data centers to prevent the servers from overheating. Prometheus Hyperscale uses a unique liquid cooling system that dramatically outperforms traditional air-cooling methods, reducing energy consumption by up to 50%. This system also utilises deep underground water reservoirs and captures the waste heat to reuse or sequester it. It’s believed that Prometheus Hyperscale’s flagship project will be the first hyperscale data center in the United States to combine liquid heat transfer and heat reuse technologies.

Founded by Trenton Thornock, an experienced leader in energy, finance and infrastructure, Prometheus Hyperscale’s flagship project in Evanston, Wyoming, promises to be the most advanced sustainable data center in the United States, and one of the largest in the world, when it becomes operational in 2025/26. The 1GW-capacity developed site will cover an area of 640-acres (one square mile), making it approximately three quarters the size of New York’s Central Park. Four further sites are currently earmarked across Arizona and Colorado.

As Chairman, Mr. Looney will ensure the successful execution of Evanston as well as Prometheus’s broader business goals. His appointment comes following the recent announcement that Trevor Neilson, a renowned climate technology entrepreneur and philanthropist, will serve as the company’s President.

It’s estimated that $1 trillion will be invested in the U.S. in data centers in the next five years – with an additional $1 trillion internationally.

Trenton Thornock, Founder and CEO of Prometheus Hyperscale commented: “Having Bernard Looney join as Chairman is a tremendous step forward for Prometheus. Bernard’s track record and transformative leadership in the energy sector aligns perfectly with our vision for the future of data centers. His insights, as well as his extensive operational and project delivery experience, will be invaluable as we bring our flagship project in Evanston, Wyoming to life and set new benchmarks for sustainable digital infrastructure.”

Trevor Neilson, President of Prometheus Hyperscale, commented: “Bernard is the perfect person to guide Prometheus as we form partnerships across the energy sector to access low-carbon electrons that will power the future of AI. His extensive industry experience and leadership will be instrumental as Prometheus establishes itself at the forefront of sustainable data center operations.”

Bernard Looney commented: “I am delighted to join Prometheus Hyperscale at this pivotal moment as the world grapples with the intersection of AI, Energy and Sustainability. Innovative power solutions are desperately needed to ensure that AI is unleashed to tackle some of the biggest global challenges including healthcare, economic growth, and the energy transition. We must work to find solutions that lead to Net Positive AI – where the benefits to our world outweigh any costs. The flagship Evanston project is one such solution and I look forward to lending a helping hand, working alongside Trenton, Trevor, and the entire Prometheus team to help bring this vision to life. I can’t imagine a more exciting challenge.”
